(CNN) — In some ways, a catastrophe of this magnitude could not have happened in a worse place. Or at a worse time of year.

We’re hearing a lot about the economic dislocation of thousands of Gulf fishers and their families — and rightly so. But the oil disaster is a much larger calamity than the Gulf itself. It’s not just a regional disaster. It has hemispheric implications.

The Gulf is a large region, but its natural importance is even more outsized, disproportionate to its area. The Gulf is the hourglass pinch-point for millions of migrating creatures that funnel into, breed in, migrate through and then fan out of it to populate an enormous area of the continents and coasts. Anything that affects living things inside the Gulf affects living things far outside it.

Certain animals that normally inhabit the open Atlantic travel to the Gulf to breed. Two such species, both endangered, breed nowhere else. The world’s most endangered sea turtle, the Kemp’s ridley turtle, ranges throughout the west Atlantic as far north as New England. But it breeds only in the Gulf. Many are now heading there to lay their eggs on remote beaches. Turtles are showing up on beaches debilitated by oil.

Oil kills sea turtles by both ingestion and direct toxicity, and by stressing and suppressing their immune systems. Adults are vulnerable, but hatchlings will have an even harder time.

Atlantic bluefin tuna — the most high-priced ocean fish in the world — have declined by about 90 percent since the 1960s due to overfishing. Their west Atlantic population ranges the East Coast of the U.S. and Canada and far out to sea, but the Gulf of Mexico is the giant fish’s only known breeding area. Spring is their breeding season.

According to a web tool that puts the slick over your home region, the vast area of surface oil is now bigger than Massachusetts, Connecticut and Long Island combined. It overlaps the tracked movements of breeding bluefin tuna. Consequently, their eggs and larvae are presumably being bathed in a toxic soup of oil and dispersant.

Dispersant, which is toxic by itself, also makes the petroleum more toxic. Instead of remaining concentrated at the surface, dispersed oil pollutes the entire water column. Instead of evaporating, the toxic components remain in the water. And because it’s dissolved, it passes more easily across gills and into digestive systems. Planktonic animals become disoriented or die.

Meanwhile, of course, mats of oil are washing ashore. No amount of boom will protect waterbirds like pelicans, gulls and terns, because diving into the water for fish is how they eat. In the Gulf in May, with the oil gushing, were loons, gannets, various kinds of herons and terns. Also there were black skimmers that had spent the winter there but would soon leave to migrate north and, depending on species, breed all along the coast from the southern states to as far north as the Maritimes, and lakes across much of Canada.

Some of the longest-distance migrants on Earth are various sandpipers, plovers and other shorebirds, many of which winter as far south as Patagonia and breed as far north as the high arctic. Perhaps a million cross the Gulf in May, and when they reach the U.S. coastline, they must stop to rest and feed. Problems with habitat and food supply have reduced many of their populations 50 to 80 percent in the past 20 years. And now this. When oil was just starting to smudge some of the birds on beaches now thick with it, I saw sanderlings, ruddy turnstones, black-bellied plovers and other such northbound birds.

Even among those that do not get heavily oiled, many will not make it. The birds’ energy budgets operate on thin margins of food intake against exhaustive expenditure in long-distance flight. They will not bear the additional cost of feathers sticking and functioning inefficiently, and many such birds will drop out on their way north.

Migrating peregrine falcons traveling north from South American wintering areas, destined for nesting areas as far as Greenland, are also crossing the Gulf’s marshes. Preferentially picking off birds whose flight seems compromised, falcons will be getting disproportional doses of oil.

All these birds can live decades and take years to mature, so adult birds killed by oil this year will mean populations reduced for years to come. This is a calamity not just in space but in time as well.

Some animals may be rescued. Less possible to cleanse is the anguish on the faces and in the hearts of fishing families. Oil companies can drill, and they can buy votes in Congress, but apparently they can’t do much else.

Now that the reckoning is here, it becomes a little easier to see that we fool ourselves with the apparent cheapness of subsidized oil and that a healthy environment is priceless beyond reckoning.

Why do we fail to know this always, in our bones? The Gulf is not a thing unto itself. Neither is the oil eruption. We are all Gulf victims now.

The innocents of the gulf suffer because of our culture of oil. Also our culture of political game- playing. I wonder if anything will truly change world-wide. I hear Canada is preparing to start a deep-water drilling operation on the east coast.

It is such an overwhelming tragedy. Our long-term environmental penalty for this action has not fully been realized yet. Unfortunately it will slowly reveal itself over time much to our misfortune! Your CNN report is an awareness “shot in the arm.” Lets hope this will wake the world about what we, the humans, are destroying in our quest for a material life. I grieve for humans that will not change and I grieve for the wild ones that are paying the penalty now. But humans will pay ultimately..

We can’t just read your analysis and lay back content because it is happening somewhere besides where you live. It will touch everyone like you point out.

We need to take individual action to stop this madness. Each person can ultimately change our culture of oil. — barbara

Yes, yet another incomprehensible tragedy that breaks the hearts of us all so deeply that unfortunately we return to our all too useless and pernicious human defenses of fantasy and denial (e.g. it will be okay, it wasn’t that bad, what was it that happened on the gulf?)

Perhaps it would be helpful to learn about how petroleum is linked to almost every decision we make as consumers. Perhaps a diagram to show how just changing one small habit (e.g. shutting lights off, reusing bags, buying unpackaged bulk items) can make a difference. We have miles to go, but every inch counts.

Like so many have said, after the well is finally closed, people will start assessing the damage. It will take years and years. I don’t think anyone knows what the consequences will be, both for animals and people. My hope is that this disaster, that some are so quick to play down, may become a catalyst for some positive and mitigating measures. Maybe scientists and NGOs can successfully argue for the creation of MPAs and sanctuaries in the Gulf and elsewhere in the network of habitats that these creatures need to survive. Maybe authorities in Europe, Japan and the USA will finally give the Bluefin some time and space to rebound. Nature will need plenty of time to recover from this.
